Abstract

Disclosed is an encryption method. The encryption method comprises: obtaining a binary image as an original image; arranging the original image according to a coordinate sequence to generate a first one-dimensional array; obtaining the panel number of a terminal; according to the panel number of the terminal, encrypting the first one-dimensional array to generate a second one-dimensional array; and in accordance with the coordinate sequence, enabling the second one-dimensional array to generate an encryption image. Also disclosed at the same time are a decryption method, a server, a terminal and an encryption/decryption system. The present invention can be applied to the digital image anti-counterfeiting technology of terminal products, and the application is simple.
